BACKGROUND OF THE INVENTION

Pain is one of the most frequent symptoms for which patients seek medical intervention. Pain may be classified as acute or chronic. Acute pain may be generally associated with excessive noxious stimulus resulting in a severe distressful sensation whereas chronic pain may be associated with physiological changes resulting from tissue or nerve injury leading to hyperalgesia, an increased amount of pain associated with a mild noxious stimulus, or allodynia, a pain induced by a non-noxious stimulus.

Neurogenic pain is a neurological disorder caused by insult to peripheral nerves, resulting in chronic pain and varying combinations of sensory symptoms, including paresthesia, loss of sensation, and even motor weakness. Neurogenic pain may be long-lasting, and may develop days or month following the injury. Often, this type of chronic pain may be observed in diseases affecting the peripheral nervous system, such as nerve compression syndromes, cutaneous sensory neuropathies and polyneuropathies (of which diabetic neuropathy may be the most well-known).

Amongst the various types of chronic pain, understanding and management of neurogenic pain remains a considerably challenging task for researchers and clinicians. Despite the rapid development of neuroscience and the discovery of new pharmaceutical compounds, a need continues to exist for an effective treatment based on a basic understanding of the contributing molecular mechanisms of neurogenic pain.

Neurogenic pain involves alterations in the function of both the peripheral and central nervous system, postulated to be caused by changes in mechano-insensitive peptidergic nociceptors referred to as “silent” or “sleeping” nociceptors, which are chemo-sensitive and respond to noxious chemicals typically released in response to tissue or nerve trauma. Once sensitized, the phenotype of the nociceptors can be altered, whereby the formerly “silent” or “sleeping” nociceptors become “polymodal” or “awake” nociceptors (C fibers), which release significant amounts of pro-inflammatory neuropeptides, such as calcitonin gene-related peptide (CGRP) or substance P (SP), initiating neurogenic inflammation in combination with enhancing action potentials, thereby resulting in increased nociception.

Following nerve injury, increased excitability and sensitivity is observed in the cell body of the injured dorsal root ganglia neurons and neighboring intact afferent neurons. This enhanced stimulation involving the primary afferent neurons is defined as peripheral sensitization, which is mediated by increased expression of the transient receptor potential (TRP) family of non-specific cation channels, including transient receptor potential cation channel subfamily V member 1 (TRPV1), which is expressed in C fibers and Aδ fibers. Another mechanism leading to peripheral sensitization includes the accumulation of voltage-gated sodium channels at the site of the injured nerve and at the dorsal root ganglion, resulting in abnormal ectopic excitability of afferent neurons. These changes may be perceived as spontaneous positive sensations, such as paresthesia (a sensation of tingling, burning, pricking, or numbness of skin) or dysthesia (an unpleasant, abnormal sense of touch).

Central sensitization, defined as the activation of second order nociceptive neurons in the dorsal horn of the spinal cord by peripheral nerve damage, results from the release of glutamate, SP, or other transmitters or cytokines, such as adenosine-5′-triphosphate (ATP), chemokine (C—C motif) ligand 2 (CCL2), or interferon gamma (INFγ), from the central terminals of primary nociceptive afferents in the dorsal horn. The overall effect of these changes may be prolonged excitability of the spinal cord neurons (long-term potentiation).

Further contributing factors to the development of neurogenic pain include the involvement of spinal cord microglia and astrocytes in enhancing pain, whereby ATP-activated microglial P2X4 and P2X7 receptors stimulate the p38 mitogen-activated protein kinases (p38-MAPK) signalling cascade, resulting in release of substances such as brain-derived neurotrophic factor (BNDF), down-regulation of potassium/chloride cotransporters, and diminished inhibitory neurotransmission (GABAergic inhibition).

Additionally, following an injury, various inflammatory substances such as histamines, prostaglandins, or cytokines, may be released from inflammatory cells which have migrated through the blood to the site of the injured tissue. When the injury results in nerve damage, the peripheral terminals of sensory neurons may be activated, resulting in inflammation characterized by the release of neuropeptides, such as CGRP, SP, or calcitonin, from the C fiber terminal, which can lead to vasodilation, edema, or pain. As such, neurogenic inflammation plays an integral role in the pathophysiology of neurogenic pain.

Successful treatment of neurogenic pain requires direct targeting of the receptors and transmitters involved. Conventional therapeutic strategies aim to reduce neuron excitability through alterations in ion channel activity, which may be targeted by compounds such as gabapentin or lidocaine, or modulate central neurotransmission, which may be targeted by compounds such as opioids or tricyclic antidepressants. Despite consistent efficacy observed in randomized trials and meta-analyses, the use of these agents may be limited due to debilitating side effects, such as sedation, somnolence, dry mouth, urinary retention, erythema, ataxia, or the like, or combinations thereof. Moreover, patients using these compounds must be closely monitored and dose tapering may be required to prevent withdrawal symptoms. Accordingly, a need exists for a novel alternative characterized by maximal therapeutic efficacy, minimal toxicity, and low incidence of side effects.

A method of using the inventive composition can include transdermally administering the inventive composition including an amount of sugar or sugar alcohol, an amount of alkalizing agent, and an amount of vehicle, whereby the inventive composition is formulated for transdermal administration.

As to particular embodiments, the method of using the inventive composition can further include transdermally administering the inventive composition to an external surface of a body to alleviate one or more disorder symptoms, for example to decrease neurogenic pain, or to treat one or more disorders, for example to decrease neurogenic inflammation.

As to particular embodiments, the method of using the inventive composition can further include transdermally administering the inventive composition along a nerve pathway of a nerve to decrease neurogenic pain or to decrease neurogenic inflammation of the nerve.

As to particular embodiments, transdermally administering the inventive composition can alkalize a perineural environment proximate the nerve by adjusting a pH of the perineural environment from a lesser alkalinity toward a greater alkalinity. As to particular embodiments, transdermally administering the inventive composition can decrease an amount of hydrogen ions (H+) in the perineural environment proximate the nerve.

Research suggests an association between tissue acidity and neurogenic inflammation whereby hydrogen ions (H+) may prime the transient receptor potential cation channel subfamily V member (TrpV1), thereby increasing neurogenic inflammation and corresponding neurogenic pain. Accordingly, decreasing the amount of hydrogen ions (H+) by adjusting the perineural environment from a lesser alkalinity toward a greater alkalinity may be beneficial for alleviating neurogenic pain or treating neurogenic inflammation.

As to particular embodiments, transdermally administering the inventive composition can decrease a viscosity of hyaluronic acid (also known as hyaluronan, hyaluronate, or HA), which is an anionic, nonsulfated glycosaminoglycan widely distributed throughout connective, epithelial, and neural tissues. Particularly, hyaluronic acid can be found between fascial layers, acting as a lubricant to facilitate fascial glide. As peripheral nerves, especially superficial sensory nerves, can typically be enveloped between fascial layers, decreasing the viscosity of hyaluronic acid may decrease friction or mechanical irritation of the nerves by the fascia. Research suggests that adjusting the pH of a perineural environment from a lesser alkalinity toward a greater alkalinity may result in a conformational change in the hyaluronic acid molecule resulting from a degradation of attraction forces between hyaluronic acid molecules, thereby increasing the flexibility of the hyaluronic acid polymer and correspondingly decreasing the viscosity of hyaluronic acid.

As to particular embodiments, the method of using the inventive composition can further include transdermally administering the inventive composition formulated as a fluid, such as a lotion, cream, emulsion, ointment, gel, foam, paste, oil, lipid delivery system, spray, drops, or the like, or combinations thereof, to the external surface of the body to alleviate one or more disorder symptoms or to treat one or more disorders.

As to particular embodiments, the method of using the inventive composition can further include administering one or more physical skin penetration enhancement techniques before, during, or after transdermally administrating the inventive composition to the external surface of the body to alleviate one or more disorder symptoms or to treat one or more disorders. As illustrative examples, physical skin penetration enhancement techniques can include phonophoresis, sonophoresis, iontophoresis, electroporation, radiofrequency-driven skin microchanneling, microneedles, massage, occlusion, heating, cooling, or the like, or combinations thereof.

Now referring primarily to Table 2, which evidences the results of a method of transdermally administering a particular embodiment of the inventive composition to twenty-six subjects (indicated in column 1 as “Subject Number”) who presented with various pain-related complaints (indicated in column 2 as “Primary Complaint”).

Again referring primarily to Table 2, the method of transdermally administering the particular embodiment of the inventive composition included: i) identifying the site of one or more symptoms, typically pain, and having the subject assess their perceived pain level on a scale ranging from 0 to 10, with 0 being the least amount of pain and 10 being the greatest amount of pain (indicated in column three as “Pre-Admin Pain Level”); ii) determining the cutaneous nerve branch(es) or main nerve trunk(s) liable for the one or more symptoms; iii) confirming the liability of the cutaneous nerve branch(es) or main nerve trunk(s) for the one or more symptoms by palpation; and iv) transdermally administering the inventive composition along the nerve pathway of the cutaneous nerve branch(es) or main nerve trunk(s) liable for the one or more symptoms, focusing on areas where the cutaneous nerve branch(es) or main nerve trunk(s) emerge superficially from deeper regions. Generally, the inventive composition was transdermally administered for a time period of about sixty seconds. Following, the subject reassessed their perceived pain level at about five minutes after the transdermal administration of the inventive composition (indicated in column four as “5 Minutes Post-Admin Pain Level”) and again at about twenty-four hours after the transdermal administration of the inventive composition (indicated in column six as “24 Hours Post-Admin Pain Level”).

Again referring primarily to Table 2, the mean pre-administration perceived pain level was 5.7/10 whereas the mean five minutes post-administration perceived pain level was 0.4/10, resulting in a mean 95% reduction in perceived pain level (each subject's percent reduction in perceived pain level indicated in column five as “Percent Reduction in Pain Level”) in relation to the pre-administration perceived pain level. The mean twenty-four hour post-administration perceived pain level was 1/10, resulting in a mean 84% reduction in perceived pain level (each subject's percent reduction in perceived pain level indicated in column seven as “Percent Reduction in Pain Level”) in relation to the pre-administration perceived pain level.

A method of producing a particular embodiment of the inventive composition can include combining an amount of sugar or sugar alcohol, an amount of alkalizing agent, and an amount of vehicle; and formulating the inventive composition for transdermal administration.

As used herein, the term “combination or combining” refers to any method of putting two or more materials together. Such methods include, but are not limited to, mixing, blending, commingling, concocting, homogenizing, ultrasonic homogenizing, incorporating, intermingling, fusing, joining, shuffling, stirring, coalescing, integrating, confounding, joining, uniting, creating a stable suspension of two immiscible liquids via any number of means such as emulsions, or the like.

As to particular embodiments, the method of producing a particular embodiment of the inventive composition can include combining the sugar or sugar alcohol, alkalizing agent, and vehicle, whereby each can be combined in an amount as described above.

As to particular embodiments, the method of producing a particular embodiment of the inventive composition can further include combining one or more additional components to formulate the inventive composition, whereby the one or more additional components can be as described above or can be other additional components.

As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of a pain relieving system and methods for making and using such pain relieving systems including the best mode.

As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.

It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of a “combination” should be understood to encompass disclosure of the act of “combining”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “combining”, such a disclosure should be understood to encompass disclosure of a “combination” and even a “means for combining”. Such alternative terms for each element or step are to be understood to be explicitly included in the description.

In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.

All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result. Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.

Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.

Thus, the applicant(s) should be understood to claim at least: i) each of the pain relieving systems herein disclosed and described, ii) the related methods disclosed and described, iii) similar, equivalent, and even implicit variations of each of these devices and methods, iv) those alternative embodiments which accomplish each of the functions shown, disclosed, or described, v) those alternative designs and methods which accomplish each of the functions shown as are implicit to accomplish that which is disclosed and described, vi) each feature, component, and step shown as separate and independent inventions, vii) the applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and apparatuses substantially as described hereinbefore and with reference to any of the accompanying examples, x) the various combinations and permutations of each of the previous elements disclosed.
